Wine Cellar Climate Monitor Kit with Arduino Nano + HC-05
Wine Cellar Climate Monitor Kit – Arduino Nano BLE OTA Configuration & EEPROM Persistence
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Maintaining perfect wine storage conditions requires stable temperature and humidity — yet commercial monitors lack programmability. This kit lets you build a compact, self-contained climate monitor that saves custom thresholds in EEPROM and accepts wireless updates over Bluetooth. Your wine stays protected through power cuts and seasonal changes without ever touching the hardware.
What You'll Build
You will assemble a fully functional Arduino Nano–based monitor that reads temperature and humidity with a DHT22 sensor, displays live readings and set limits on a 0.96-inch OLED, and drives a relay to switch a fan or dehumidifier. All thresholds are set from your phone using a simple BLE app and written directly to the Nano’s EEPROM. After a blackout, the system boots straight back with your exact preferences — no reconfiguration, no data loss.
What You'll Learn
- Program Arduino Nano’s EEPROM to store temperature and humidity thresholds permanently
- Establish wireless BLE communication with an HC-05 module for phone-based OTA configuration
- Interface a DHT22 sensor and 0.96-inch OLED to display real-time climate data
- Drive a 5V relay module to automate cooling or dehumidifying equipment when limits are crossed

Who This Kit Is For
Intermediate makers aged 15-18 and beyond who want a real-world embedded project. Ideal for CBSE Class 12 students building a persistent-storage demonstration, B.Tech ECE students exploring BLE and non-volatile memory, or ATL Tinkering Lab teams prototyping a wine cellar automation system. Also a perfect hands-on gadget for wine enthusiasts who prefer tunable, phone-controlled monitoring over a static wall thermostat.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.

Do I need to reprogram the thresholds every time the power goes out?
No. The Arduino Nano stores your temperature and humidity limits in its EEPROM, which is non-volatile memory. After a power cycle, the system automatically reads the saved values, so your wine cellar monitor resumes immediately without reconfiguration.
How do I change the climate thresholds once the unit is installed?
Simply open the BLE app on your phone, connect to the HC-05 module, and adjust the settings. The new values are written to the EEPROM in real-time over the air, and the relay will respond to the updated limits.
Can this kit control both a cooler and a humidifier?
The kit includes one 5V relay module, so it can control one appliance (for example, a cooling fan). With slight expansion, you can add a second relay to manage a humidifier. Our AI companion can guide you through the wiring and code changes.
Wine Storage — Nano saves configuration to EEPROM over BLE from phone. Settings persist power cycles. Compact OTA config.
